Frequently Asked Questions - 433201A Extech
How do I replace the battery in my Extech 433201A?
To replace the battery, turn off the meter and remove the screw on the back cover. Replace the old 9V battery with a new one (NEDA 1604A or equivalent). Ensure correct polarity before closing.
What does the 'OL' reading mean on the display?
'OL' stands for Over Limit. It indicates the measured value exceeds the selected range. Switch to a higher range or use auto-range mode.
Can I measure AC current with this multimeter?
Yes, the Extech 433201A can measure AC current up to 10A. Set the dial to the ACA position and connect the leads in series with the load.
How do I test a diode?
Set the rotary switch to the diode symbol (→+). Connect the red lead to the anode and black to the cathode. The display shows the forward voltage drop; a good diode reads about 0.5-0.8V.
What is the accuracy for DC voltage measurements?
The accuracy is ±(0.5% + 2 digits) for DC voltage up to 600V. For more details, refer to the manual.
Does the meter have an auto power-off feature?
Yes, the Extech 433201A has an auto power-off after approximately 30 minutes of inactivity to save battery life.
How do I clean the multimeter?
Use a damp cloth with mild soap to clean the case. Do not use abrasives or solvents. Keep the input terminals clean and dry.
Can I use this multimeter on a car battery?
Yes, it can measure car battery voltage (12V DC). Set to DC Volts and connect red to positive, black to negative. Ensure you use the 20V range for best accuracy.
What type of fuse does the 433201A use?
The meter uses a 10A/250V ceramic fuse for the current input and a 500mA/250V fast-blow fuse for low current ranges. Replace only with specified fuses.
How do I calibrate the Extech 433201A?
Calibration should be performed by a certified technician using a calibrated source. Annual calibration is recommended for accuracy. Contact Extech or a service center.
